Hi all,

At the moment I can only access gdisk when I boot with the standalone kernel. I'd like to create a 1TB partition table table. Could anybody share the partition table? I flashed the bootloader earlier so I can use GPT partitions on my NWSP2 Classic.

Hi Nabil89,

So it seems you used fvdw-sl console so why you did not use its install script ? So use action "Install fvdw-sl firmware" :scratch

I did use the install script. But it stops after I select my device and this is shown:

fdisk: can't open '/dev/sda'
diskid=none

There was an error detecting device sda, this device is required to install firmware.
Installer will exit.

I also can't open fdisk, gdisk only.

And this is the output in gdisk:

Code: Select all

root@fvdw-sta-kirkwood:/ # gdisk -l /dev/sda
GPT fdisk (gdisk) version 0.8.5

Indeed you have an amazing disk !

Code: Select all

First usable sector is 34, last usable sector is 18446744073709551582

So A very very large disk :shocked :shocked :shocked
18446744073709551582 <=> >1 000 000 000 TB :pound

I think it is related with your wrong mbr table or it is a defective disk.

So still from a standalone session, run

Code: Select all

dd if=/dev/zero of=/dev/sda bs=1M count=1

and post again

Code: Select all

gdisk -l /dev/sda

Note: anyhow in its current state, you will never be able to create a partition table on the disk

I think (and hope) it's related with the wrong mbr and able to fix it. This is the output:

Code: Select all

root@fvdw-sta-kirkwood:/ # dd if=/dev/zero of=/dev/sda bs=1M count=1
dd: writing '/dev/sda': No space left on device
1+0 records in

So no progress...

we try another way from the standalone session:

Code: Select all

gdisk /dev/sda

and use the experts’ menu (Enter x) Then try to set a new protective MBR (Enter n and follow any dialogue questions)
So go back to the main menu (Enter m) and write the changes (Enter w)

Then post again

Code: Select all

gdisk -l /dev/sda

No positive result :(

Code: Select all

I am sorry but it seems you have a damaged disk and I have no more idea.

Wait fvdw maybe he will have other suggestions

Ok i'll wait. Thanks for your help so far.
